I can type like 45 WPM on my phone keyboard right now. I'm definitely faster on a full size keyboard, but I'm not sure if I would be faster on this small keyboard. I know a lot of people wanted keyboard like this when the iPhone first came out, but now with a lot of practice using mobile keyboards, I'm not sure it's needed.
One of the main arguments for hardware keyboards was you could type without looking. I don't really look at my phone keyboard when typing, I roughly know the spacing of the letters. Plus auto correct is really good at this point, so when I do make mistakes the phone usually just corrects them.
The only use case I could see for this is if the keyboard had control/alt/esc keys - in that case shelling into a machine on my phone might become slightly more efficient than an onscreen keyboard.
